I bought my girlfriend a Wii some time ago and before playing any game we spent 2 hours making Mii's of ourselves and all the people we know. A Mii - for those not in the a know - is your Wii avatar. It is associated with your personal stats on games such as WiiFit and WiiSport. Now Mii's are downright cartoony, but we tried to make them as lifelike as possible. After you're done it; (read more)

I feel a little left out some times on the internet as many (but certainly not all) of my bloggy friends are English or American. So, just to fill you in, the 26th of January is Australia Day and it commemorates the landing of our first fleet in 1788 and the planting of the British flag in what was then known as New Holland and is now known as Sydney Cove, New South Wales, Australia. Most people celebrate the day with a public holiday, a beer or two, a barbi and the TripleJ Hottest 100.

An interesting analysis in Environmental Research Letters of the accuracy of media reporting of climate-related sea level rise. The premise: That the mass media associates sea level rise with climate change and reports on it frequently, yet the scientific community remains dubious of the media's accuracy. So how god or bad is the situation really? The authors examined the accuracy of reporting between 1989 and 2009 by seven prominent US and UK newspapers:New York TimesWashington PostLos Angeles ........ Read more »

Phenomenally beautiful math was the main highlight of this week, I’d say, although none of it for the very faint of heart.

Tevatron is again at the forefront of the blogosphere mostly due to Jester and Lubos. Top quark seems the main suspect to put an end to the domain of the Standard Model in particle physics. Indeed, years and years of confirmations cannot last forever and somewhere some odd behavior must appear. But this is again [...]... Read more »

Bingham's model predicts that the information for relative phase is the relative direction of movement. The first direct test of this hypothesis was the experiment that followed on from my learning study, in which we systematically perturbed the various candidate information variables to see which affected performance in the perceptual judgement task.I like this study a lot, if I do say so myself. It's a serious attempt to make a strong test of the model's predictions, and we invested a lot of t........ Read more »

Before we get too far ahead of ourselves, let's remember that dark energy being a cosmological constant fits the data very well and has for years. That said, experimental constraints allow for dark energy actually being an exotic form of phantom energy. (So for the time being we have to allow for the possibility and work out the details.) This was recently done by Dabrowski and Denkiewicz.

In his paper purporting to show that a beneficial, baby-making “religion gene” will sweep through a population and eventually make everyone religious, Robert Rowthorn ignores this inconvenient fact: nearly everyone in the world is already religious. Here is how it breaks down:
Because fifty percent of the “Non-Religious” group is theistic but not “religious,” we can [...]... Read more »

I've said it before, and I'll say it again - pathogens are devious little bastards:
Discovery of a Viral NLR Homolog that Inhibits the Inflammasome
In order to respond to a virus, a cell first has to recognize that it's there. There are a lot of ways the cell tries to do this - some receptors (like the TLRs I study) look for features that are unique to pathogens that are outside the cell. Others look for molecules (like DNA and RNA) that are shared between us and pathogens, but are in the wron........ Read more »

When it was first described in 1993, Mononykus was one of the strangest dinosaurs known. It had the slender, light build of some of the “ostrich mimic” dinosaurs, yet it possessed two stubby, one-clawed hands and a few other subtle characteristics that placed it in a new group called the alvarezsaurs. Since that time, multiple [...]... Read more »

As health professionals, we often assume that our patients understand what we tell them and can read the information sheets we expect them to understand.
